>The latency is what is getting me though. 0.4 round trip every time. Tested from multiple machines including a phone on LTE to get the same response time. That should theoretically mean I am right next to the machine which doesn't make sense across three different connections.

It means your 3 different connections have decent connectivity to whatever host currently responds to ping for that IP. You cant really derive much more than that from a ping. If it has been there since 1994 it might have been decommed and the IP reassigned. I would suggest a scream test to be honest, especially if you have orders to remove it anyway, seeing if the pings stop responding when you remove the power or networking will tell you more.
